This article's authors use linked administrative data from the Social Security Administration (SSA) and the Department of Education's Rehabilitation Services Administration to evaluate SSA's investment in services provided by the federal-state Vocational Rehabilitation (VR) program. A unique data resource permits a comparison of the value of SSA payments to state VR agencies for services provided to disability program beneficiaries who find and maintain a substantial level of work with the value of the cash benefits those beneficiaries forgo because of work. The authors find that the value of cash benefits forgone by beneficiaries after applying for VR services is substantially greater than the value of SSA payments to state VR agencies for those services, although the portion of the difference that is attributable to VR services cannot be determined.

Congress established the Social Security Disability Insurance (DI) program in 1956, after more than 20 years of debate. From the outset of the debate, however, there had been general agreement that the DI program should be for workers with substantial work histories, be funded through payroll taxes, include stringent disability criteria, provide modest benefit levels, and require return-to-work supports. Using administrative data on current DI beneficiaries, this issue paper examines how the program reflects those original tenets as it nears its 60th anniversary.

Workplace injuries and illnesses are an important cause of disability. States have designed their workers' compensation programs to provide cash and medical-care benefits for those injuries and illnesses, but people who become disabled at work may also be eligible for Social Security Disability Insurance (DI) and related Medicare benefits. This article uses matched state workers' compensation and Social Security data to estimate whether workplace injuries and illnesses increase the probability of receiving DI benefits and whether people who become DI beneficiaries receive benefits at younger ages.

This article introduces and highlights the key findings of the other articles presented in this special issue, which focuses on the employment of beneficiaries in the Social Security Disability Insurance and Supplemental Security Income programs.

Using linked administrative data from program and earnings records, we summarize the 2007 employment rates of working-age (18–64) Social Security disability program beneficiaries at the national and state levels, as well as changes in employment since 1996. Substantial variation exists within the population. Disability Insurance beneficiaries and those younger than age 40 were much more likely to work relative to other Social Security beneficiaries. There are also strong regional differences in the employment rates among disability beneficiaries of working age, and these differences are persistent over time.

This article presents the Supplemental Security Income (SSI) Financial Eligibility Model developed in the Division of Policy Evaluation of the Office of Research, Evaluation, and Statistics. Focusing on the elderly, the article simulates five potential changes to the SSI eligibility criteria and presents the effects of those simulations on SSI participation, federal benefits, and poverty among the elderly. Finally, the article discusses future directions for research and potential improvements to the model.
